Multimodal Analgesia in Foot and Ankle Surgery

Efficacy, Safety, and Pharmacokinetics of CPL-01, an Investigational Long-Acting Ropivacaine, in Bunionectomy: Results of a Phase 2b Study

CPL-01 (ropivacaine extended-release injection) is formulated to safely provide postoperative analgesia and reduce opioid use. Participants undergoing unilateral distal first metatarsal bunionectomy with osteotomy were randomized to receive either CPL-01 (200 mg in Cohort 1, 300 mg in Cohort 2), ropivacaine HCl (50 mg in Cohort 1, 75 mg in Cohort 2), or volume-matched placebo into the surgical site prior to closure. Participants remained in an inpatient setting for 72 hours to assess efficacy (Numeric Rating Scale [NRS] scores for pain with activity adjusted for opioid usage and rescue medication usage), safety and pharmacokinetics. Seventy-three participants were randomized and treated, and 71 participants completed the study. Participants who received 300 mg CPL-01 had a mean (SD) area under the curve from 0 to 72 hours (AUC0-72) of the NRS score with activity of 356.9 (132.82), which was lower than placebo, indicating less pain. Participants who received CPL-01 300 mg also had numerically lower mean total opioid consumption. CPL-01 was safe and well-tolerated, with no evidence of increased AEs in one group versus another. Infiltration of CPL-01 had no impact on wound or bone healing. CPL-01 showed predictable and consistent extended-release pharmacokinetics, with no indication of "dose-dumping." Ropivacaine HCl delivered 94.3-99.7% of its ropivacaine dose in the first 24 hours, the 300 mg CPL-01 dose delivered 38.5%. While this Phase 2b study was small, results demonstrated the safety, efficacy, and extended-release characteristics of this long-acting ropivacaine formulation in this surgical model, supporting further development of CPL-01 in Phase 3 clinical studies.

Efficacy of Anterior Quadratus Lumborum Block and Pain After Total Hip Arthroplasty: A Randomized Controlled Trial

BACKGROUND

Anterior quadratus lumborum block (AQLB) is one of the compartment blocks and has recently attracted attention as a new method of analgesia for postoperative hip surgery analgesia. This study aimed to compare the analgesic efficacy of AQLB in patients undergoing primary total hip arthroplasty (THA).

METHODS

There were 120 patients undergoing primary THA under general anesthesia randomly allocated to receive a femoral nerve block (FNB) or an AQLB. The primary outcome was total morphine consumption over the initial 24-hour postoperative period. Secondary outcomes included the pain score evaluation while at rest and during active and passive motion over the 2 days following surgery and the manual muscle testing of the quadriceps femoris. The numerical rating scale (NRS) score was used for evaluating the postoperative pain score.

RESULTS

There were no significant differences between the 2 groups concerning morphine consumption within 24 hours after surgery (P = .72). The NRS score at rest and passive motion were similar at all-time points (P > .05). However, there was a statistically significant difference in pain reported during the active motion for the FNB group compared to the AQLB (P = .04). No significant differences were found between the 2 groups concerning muscle weakness incidence.

CONCLUSION

Both AQLB and FNB demonstrated adequate efficacy for postoperative analgesia at rest in THA. However, based on our study, whether AQLB is inferior or noninferior to FNB as an analgesic method for THA was inconclusive.

Predictors of opioid requirement among patients receiving free flap reconstruction to the head and neck

BACKGROUND

Opioids are a part of standard of care treatment of acute, severe postoperative pain. However, increased opioid requirements have been shown to be associated with increased postoperative complications, morbidity, and mortality. The aim of this study was to identify potential predictive factors associated with increased or decreased opioid requirements after free tissue transfer (FTT) to the head and neck.

MATERIALS/METHODS

A retrospective review was conducted on subjects who underwent head and neck reconstruction (HNR) from 2015 to 2021 at a single tertiary care center. Patients with inpatient stay over 10 days and those receiving fentanyl for sedation purposes were excluded due to EMR limitations and confounding, respectively. The total dose of opioid medication each patient received was calculated and summed using morphine milligram equivalents (MME). Statistical analysis was conducted using poisson regression and multivariable regression models.

RESULTS

Two hundred and ninety-one patients were included. The mean opioid requirement for all subjects was 228.6 (SD 250.0) MMEs during their entire postoperative stay and the mean length of stay was 6.0 (SD 1.7) days. An established opioid prescription prior to surgical resection was the greatest predictor of increased risk for opioid requirement according univariate and multivariate analysis 2.356 (2.321-2.392), p ≤ 0.0001 and 1.833 (1.802-1.863), p ≤ 0.0001, respectively. Fibula transfers were associated with higher opioid requirements while scapula transfers were associated with decreased opioid requirements compared to other free tissue transfer types.

CONCLUSION

Preoperative opioid use was associated with higher postoperative opioid requirements. Multimodal pain management (MMPM) was not associated with a decreased opioid requirement; however, further studies are needed to investigate the hierarchy, dosing, and timing of MMPM in relation to opioid requirements and pain control.

Pain relief after major ankle and hindfoot surgery with repetitive peripheral nerve blocks: A feasibility study

BACKGROUND

Major ankle and hindfoot surgery (e.g., ankle, triple and subtalar arthrodesis) typically causes severe postoperative pain, especially the first two postoperative days. Current modalities of postoperative analgesic treatment often include continuous peripheral nerve blocks of the saphenous and sciatic nerves via catheters in order to extend the duration of pain- and opioid-free nerve blockade to 48 h. Unfortunately, the 48 h-efficacy of continuous infusion via a catheter is reduced by a high displacement rate. We hypothesised that one-time repetition of the single injection peripheral nerve blocks would provide effective analgesia with a low opioid consumption the first 48 postoperative hours.

METHODS

Eleven subjects preoperatively received a popliteal sciatic and a saphenous single injection nerve block with a protracted local anaesthetic mixture. Surgery was performed under general anaesthesia. The one-time repetition of the single injection nerve block was carried out approximately 24 h after the primary nerve block. The main outcomes were pain and cumulative opioid consumption during the first 48 postoperative hours.

RESULTS

Nine of the 11 (82%) patients had effective analgesia without opioids during the first 48 postoperative hours. Two patients each required a single dose of 7.5 mg of oral morphine equivalents after 43 h.

CONCLUSION

One-time repetition of single injection saphenous and sciatic nerve blocks consistently provided effective analgesia practically without opioids for 48 h after major elective ankle and hindfoot surgery.

Management of Anxiety for Ambulatory Hallux Valgus Surgery With a Virtual Reality Hypnosis Mask: Randomized Controlled Trial

BACKGROUND

The purpose of this study was to evaluate the impact of using virtual reality masks for the management of preoperative anxiety and its impact on postoperative and predischarge anxiety as well as postoperative analgesia during outpatient hallux valgus surgery.

METHODS

From June 2020 to September 2021, preoperative anxiety of patients scheduled for a percutaneous hallux valgus surgery were analyzed using the State Trait Anxiety Inventory (STAI) questionnaire completed during the consultation. All patients with major anxiety, defined as a STAI score above 40, were included in a randomized prospective comparative single-center study. Sixty patients were included in the study and randomized into 2 arms of 30 patients according to whether or not they underwent a preoperative hypnosis session with a virtual reality mask before surgery.

RESULTS

There was an improvement in the postoperative (42.5 vs 45.2, P < .04) and predischarge (25.3 vs 30.2 P < .03) anxiety scores in the group that used the mask before the procedure. There was a notable decrease in immediate higher-level postoperative analgesics such as morphine or ketamine (3.3% vs 26.6%, P < .03) in the arm using the mask.

CONCLUSION

In this study cohort undergoing percutaneous hallux valgus surgery, we found that use of a virtual reality hypnosis mask before surgery modestly reduced postoperative and predischarge anxiety as well as early postoperative consumption of higher-level analgesics in adults with significant preoperative anxiety.

Accuracy of Pain Tolerance Self-assessment Versus Objective Pressure Sensitivity

INTRODUCTION

Effective treatment of postoperative pain after elective surgery remains elusive, and the experience of pain can be variable for patients. The patient's intrinsic pain tolerance may contribute to this variability. We sought to identify whether there was a correlation between subjective report of intrinsic pain tolerance and objective measurement of pressure dolorimetry (PD). We also sought to identify whether a correlation existed between PD and Patient Reported Outcome Measurement Information System (PROMIS) scores of pain intensity, physical function, and mood. PD is a validated, objective method to assess pain tolerance. Markers of general mental and physical health are correlated with pain sensitization and may also be linked to pain tolerance.

METHODS

PROMIS scores, dolorimetry measurements, and survey data were collected on 40 consecutive orthopaedic foot and ankle surgery patients at the initial clinic visit. Patients were included if they had normal sensation on the plantar foot and no prior surgery or plantar heel source of pain.

RESULTS

Objective dolorimetry data reflecting 5/10 pain for the patients were 24 N/cm2 (±8.9). Patients estimated their pain threshold as 7.3/10 (±2.1). No correlation was found between objective and subjective pain threshold identified. A moderate negative correlation of R = -0.44 was observed regarding PROMIS-M with dolorimetry data (P < -0.05). PROMIS-M score >60 had a significant decrease in pain threshold to 15.9 ± 8.5 N/cm2 compared with 25.7 ± 8.9 N/cm2 for those who were less depressed with a PROMIS<60 (P < 0.05).

CONCLUSION

Subjective pain tolerance is not correlated with the patient's own objective pain threshold or markers of mental health and should not be used to assist clinical decision making. PROMIS-M is inversely correlated with objective pain. Higher PROMIS-M scores are associated with a lower objective pain threshold.

Acute postoperative pain management protocols in podiatric surgery within Australia: a Delphi study

Background

There is limited evidence in the literature to describe an analgesic protocol that takes into consideration the extent of foot and ankle surgery. The aim of this study was to develop a guide for acute postoperative pain management for podiatric surgery in Australia, and to identify opportunities to improve the current list of scheduled medicines available to podiatric surgeons.

Methods

A Delphi method involving 3 survey rounds was employed for this study. Twelve expert panellists in the field of podiatric surgery and anaesthesiology were invited to participate, and 10 panellists remained by the end of the study. Round 1 involved 15 open-ended questions. These answers formed the basis of the 55 statements that were developed for the following 2 survey rounds, where panellists rated the appropriateness of each statement on a 9-point Likert scale. The third survey round was an opportunity for panellists to revise their answers to each statement in light of the majority response.

Results

For mild acute postoperative pain, non-opioid oral analgesics were recommended as an appropriate management option. For moderate and severe acute postoperative pain, both non-opioid and opioid products were found to be appropriate by the majority. It was agreed that oral opioids be reserved for breakthrough pain at all severity levels. All other statements in the Delphi study pertaining to drug hypersensitivities or allergies, stratification of pain management, opioid prescription concerns, and access to pain medications were accepted as appropriate by the majority of panellists.

Conclusion

The agreed approach to acute postoperative pain management for podiatric surgeons in Australia was with a stepwise approach, utilising multimodal therapy, and reserving oral opioids for breakthrough pain. Additionally, there was consensus for podiatric surgeons in Australia to have wider access to alternative analgesics and anti-emetics that have similar or improved efficacies with better safety profiles.

An Update on the Practical Management of a Hexapod System in Lower Limb Orthoplastic Reconstruction for Acute Shortening and Relengthening Procedures

Background. The use of circular external fixation is a fundamental necessity in the armamentarium of a lower limb orthoplastic reconstructive surgeon. External fixation offers orthoplastic surgeons the ability to address soft tissue and osseous defects simultaneously. Using Ilizarov principles, the reconstructive surgeon must have the ability to address unique scenarios when performing orthoplastic principles. This article offers practical surgical management concepts based on experience using the TL-Hex Orthofix Truelok Hexapod System for acute shortening and relengthening. A soft tissue and osseous defect can be managed through this surgical approach as a limb salvage alternative to amputation. The information provided will lead to improved management strategies and outcomes for the practitioner and patient when presented with soft tissue and osseous defects.

Multimodal Analgesia in Head and Neck Free Flap Reconstruction: A Systematic Review

OBJECTIVE

Postoperative pain after head and neck cancer surgery is commonly treated with opioids, which are associated with considerable side effects. The objective of this study is to analyze the safety and efficacy of using multimodal analgesia (MMA) for patients undergoing head and neck cancer surgery with free flap reconstruction.

DATA SOURCES

A systematic search was conducted in PubMed, Cochrane, Embase, Scopus, and clinicaltrials.gov.

REVIEW METHODS

All studies comparing patients receiving MMA (gabapentin, corticosteroids, local anesthetic, acetaminophen, nonsteroidal anti-inflammatory drugs [NSAIDs]) vs patients receiving opioids for head and neck cancer surgery with free flap reconstruction were screened. The primary outcome was postoperative opioid usage. Secondary outcomes included length of stay, subjective pain scores, surgical/medical complications, adverse effects, and 30-day outcomes.

RESULTS

A total of 10 studies representing 1253 patients (MMA, n = 594; non-MMA, n = 659) met inclusion criteria. Gabapentinoids were the most commonly used intervention (72.9%) followed by NSAIDs (44.6%), acetaminophen (44.3%), corticosteroids (25.1%), ketamine (7.2%), and nerve block (3.4%). Eight studies reported a significant decrease in postoperative opioid usage in the MMA groups. Subjective pain had wider variation, with most studies citing significant pain improvement. There were no differences in surgical outcomes, medical complications, adverse effects, or 30-day mortality and readmission rates.

CONCLUSION

With the rise of the opioid epidemic, MMA may play an important role in the treatment of postoperative pain after head and neck cancer surgery. A growing body of literature demonstrates a variety of effective perioperative regimens.

An Innovative Pain Control Method Using Peripheral Nerve Block and Patient-Controlled Analgesia With Ketorolac After Bone Surgery in the Ankle Area: A Prospective Study

Although postoperative pain is inevitable after bone surgery, there is no general consensus regarding its ideal management. We hypothesized that the combination of ultrasound-guided peripheral nerve block (PNB) and patient-controlled analgesia (PCA) with ketorolac would be useful for pain control and reducing opioid usage. This prospective study aimed to evaluate the effectiveness of this method. This study included 95 patients aged >18 years who underwent bone surgery in the ankle area from June to December 2018. All operations were performed under anesthetic PNB, and additional PNB was given for pain control ∼11 hours after preoperative PNB. An additional PCA with ketorolac, started before rebound pain was experienced, was used for pain control in group A (49 patients) but not group B (46 patients). We used intramuscular injection with pethidine or ketorolac as rescue analgesics if pain persisted. A visual analogue scale (VAS) for pain was used to quantify pain at 6, 12, 18, 24, 36, 48, and 72 hours postoperatively. Patient satisfaction was assessed, along with side effects in both groups. VAS pain scores differed significantly between the groups at 24 hours after the operation (p = .013). All patients in group A were satisfied with the pain control method; however, 5 patients in group B were dissatisfied (p = .001), 3 owing to severe postoperative pain and 2 owing to postoperative nausea and vomiting. An average of 0.75 and 11.40 mg pethidine per patient was used in groups A and B, respectively, for 3 days. We concluded that the combined use of ultrasound-guided PNB and PCA with ketorolac can be an effective postoperative method of pain control that can reduce opioid usage.

Mitigating the opioid crisis for the lower extremity provider opioid stewardship programs

Opioids are an effective form of analgesia for pain treatment. Over prescribing of opioids agents have becom;1;e detrimental to the United States' public health. One of the most difficult challenges for any prescriber is to balance the potential benefits versus the potential risks of opioid prescribing. Addressing the opioid crisis requires an interprofessional team approach. The utilization of an opioid stewardship program provides the necessary frame work to identify gaps in the in quality and development in the implementation of a change of long standing opioid culture and practice. These programs address opioid prescribing, treatment for opioid use disorder, educational initiatives, and the use of information technology. A few acronyms have been created to assist providers to guide them when prescribing opioids. The purpose of this article is to explore the central theme of responsible opioid pain management. It will introduce, define, and defend with clinical base evidence a proposed acronym "MORPHINE" to assist and help shape prescription opioid strategies used for lower extremity pain. Implications for practicing lower extremity providers need to acknowledge the potential harm that prescribing opioids may cause to their patients. Opioid stewardship principles should become a priority in podiatric medicine and podiatric surgery.

Analgesic effect of perioperative ketamine for total hip arthroplasties and total knee arthroplasties: A PRISMA-compliant meta-analysis

BACKGROUND

Total hip arthroplasties (THA) and total knee arthroplasties (TKA) are always associated with a frequent incidence of postoperative pain. Effective pain management after surgery is quite essential for surgeons and patients. The purpose of the present meta-analysis is to evaluate the analgesic effect of perioperative ketamine after THA and TKA.

METHODS

Seven online databases, Embase, Cochrane Library, Pubmed, Web of Science, China National Knowledge Infrastructure (CNKI), China Biomedical Literature Database (CBM), and Wanfang Data were searched for the related randomized controlled trials (RCT) by August 15, 2019. The qualities of the included studies were assessed based on the Cochrane Handbook for Systematic Reviews of Interventions 5.0. The visual analog scale (VAS), morphine equivalent consumption, and the side effects were used to evaluate the postoperative analgesic effect of ketamine by meta-analysis, which was performed by Review Manager version 5.3 software.

RESULTS

The VAS scores at 6 hours, 12 hours, 24 hours, and 48 hours after surgery were statistically lower in the ketamine group. The morphine equivalent consumptions in 24 hours and 48 hours after surgery were also significantly lower in the ketamine group. For the side effects, no statistical differences in odds ratio (OR) of sedation, dizziness, hallucination, sweating, pruritus, urinary retention, constipation, version trouble, nightmares, and delirium were observed between the ketamine group and the control group. But postoperative nausea and vomiting (PONV) showed lower OR in the ketamine group.

CONCLUSION

The present meta-analysis demonstrated perioperative ketamine could be used as a safe and effective analgesic agent for THA and TKA.

Opioid Consumption and Time to Return to Work After Percutaneous Osteotomy in Foot Surgery

Surgeries involving the foot and ankle are painful procedures, with many patients unwilling to discontinue prescribed narcotics at 3 months postoperatively. Percutaneous techniques allow for smaller incisions and minimal soft tissue disruption. Fifty consecutive patients underwent outpatient percutaneous foot surgery. Data were collected on pain medication taken and time to return to work. A mean of 3.3 tablets of oxycodone were consumed during the first 2 weeks. No patient was taking narcotics after 2 weeks. Mean time to return to work was 18.9 days. Percutaneous foot and ankle surgery led to a significant reduction in narcotic consumption. [Orthopedics. 2020;43(4):e334-e337.].

Current Trends in Anesthesia Management in Hallux Valgus

Anesthesia management during hallux valgus surgery trends toward multimodal pain control. Locoregional anesthesia with peripheral nerve blocks and wound instillation increase pain control. Peripheral nerve blocks as first-line analgesia are effective with minimal side effects. Local wound instillation has a variable but positive effect with minimal negative side effects. Nonsteroidal anti-inflammatory drugs in bone-to-bone healing remain controversial; however, they reduce opiate requirements and enhance patient satisfaction. Opiate agonists remain the mainstay for postoperative pain; long-acting formulations minimize pain crises. Multimodal analgesia with locoregional anesthesia facilitate the progress of hallux valgus surgery as an outpatient procedure.

Comparison of Single-Agent Versus 3-Additive Regional Anesthesia for Foot and Ankle Surgery

BACKGROUND

This study compared the results of regional blocks containing a single anesthetic, bupivacaine, with those containing bupivacaine and 3 additives (buprenorphine, clonidine, and dexamethasone) in patients undergoing foot and ankle surgery.

METHODS

Eighty patients undergoing foot and ankle surgery over a 9-month period were prospectively enrolled and randomized to receive a peripheral nerve block containing either a single anesthetic (SA) or one with 3 additives (TA). Patients, surgeons, and anesthesiologists were blinded to the groups. Patients maintained pain diaries and were evaluated at 1 and 12 weeks postoperatively. Fifty-six patients completed the study.

RESULTS

The TA group had a longer duration of analgesic effect than the SA group (average 82 vs 34 hours, P < .05). Forty-eight hours after surgery, 93% of SA blocks, compared with 34% of TA blocks, had completely worn off. The TA group had a longer duration of sensory effects. At 3 months, 10 of 26 (38.5%) TA patients, compared with 3 of 30 (10%) SA patients, reported postoperative neurologic symptoms. Pain scores in both groups were not statistically different at 1 week or 3 months after surgery. Patients in both groups were similarly satisfied with their blocks.

CONCLUSION

Both types of nerve blocks provided equivalent pain control and patient satisfaction in patients undergoing foot and ankle surgery. The 3-additive agent blocks were associated with a longer duration of pain relief and a longer duration of numbness, as well as higher rates of postoperative neurologic symptoms. Longer pain relief may be obtained at the cost of prolonged sensory deficits.

Opioid Crisis and Acute Pain Management After Foot and Ankle Surgery

Opioid abuse has plagued the United States, with a resurgence since the early 2000s. Governmental agencies, pharmaceutical companies, patients, and physicians have all contributed to this crisis. Severe pain has been reported following foot and ankle surgery. There are current national guidelines for chronic opioid prescribing, but guidelines for acute pain have not been established. Prescribing fewer opioids, education on opioid risks, proper disposal of unused medication, and participating in prescription monitoring programs help reduce opioid abuse. Multimodal analgesia is paramount in managing pain while reducing opioid consumption after postoperative foot and ankle surgery.

Surgical fixation of pilon injuries: a comparison of the anterolateral and posterolateral approach

PURPOSE

This study looks to compare patient outcomes in those with pilon fractures fixed with the anterolateral approach versus those with the posterolateral approach.

METHODS

135 patient charts of those with surgically treated pilon fractures over a 7-year period were retrospectively reviewed, recording demographic information, fracture description, surgical intervention timeline, operative outcomes, patient outcomes, and complication rates.

RESULTS

Of the 44 included patients (32 anterolateral and 12 posterolateral), most were older than 40 years of age (65.9%) and male (63.6%). There was no difference seen between anterolateral approach and posterolateral approach tourniquet times (p = 0.80), operating room time (p = 0.40), or estimated blood loss (p = 0.73). There was also no reported difference in decrease in Numerical Rating Scale pain scores (p = 0.38), FOTO (Focus on Therapeutic Outcomes) percent increase (p = 0.13), active flexion-extension axis range of motion (p = 0.35), or inversion-eversion axis (p = 0.25) range of motion after an anterolateral approach versus a posterolateral approach. Finally, statistically similar complication rates (p = 0.75) were seen between anterolateral and posterolateral approaches, but patients who underwent a posterolateral approach surgical fixation were trending towards significantly using more post-operative outpatient opioid medications for pain control compared to those who underwent surgical fixation with an anterolateral approach (p = 0.09).

CONCLUSIONS

Pilon injuries that lend themselves to anterolateral fixation have similar outcomes peri-operatively and post-operatively compared to injuries lending to posterolateral fixation. Both approaches can be used as dictated by the injury not fearing poorer outcomes or increased complication rates. However, surgeons must be wary of high complication rates associated with all pilon injury patterns.

Evaluating the Effect of Intravenous Acetaminophen in Multimodal Analgesia After Total Hip Arthroplasty: A Randomized Controlled Trial

BACKGROUND

Postoperative pain is a significant concern of patients before surgery. Multimodal pain management is an effective method of pain control after major orthopedic surgery. Acetaminophen is the most commonly used analgesic for the management of pain. It was hypothesized that 1000 mg of intravenous acetaminophen (IA) dosed every 6 hours would significantly reduce the postoperative pain score at rest and the opioid consumption volume in patients who would undergo total hip arthroplasty (THA) when compared to a control group.

METHODS

A single-center, prospective, open-label randomized control study was conducted. A total of 97 patients undergoing unilateral primary THA were divided into 2 groups: the study group (IA) (n = 45) and the control group (n = 52). The study group received administered IA after surgery, while the control group received only a standard pain control. Both groups received a preoperative femoral nerve block and postoperative intravenous fentanyl citrate. The primary outcome was the evaluation of the pain score at rest 24 hours after surgery. The pain score was measured using the Numerical Rating Scale. The primary outcome of this study was analyzed using generalized estimating equation.

RESULTS

The IA group had a significant improvement in Numerical Rating Scale score at rest 24 hours after THA compared to the control group (-0.91, 95% confidence interval -1.56 to -0.26, P = .006), suggesting a positive effect of IA usage for pain relief. The total fentanyl citrate consumption after surgery for 24 hours was significantly lower in the IA group than those of the control group (52.07 ± 7.64 vs 57.83 ± 12.44 mg, P < .001).

CONCLUSION

Postoperative administration of IA significantly reduced the postoperative pain score and opioid consumption volume after primary THA. IA was useful as one role of multimodal pain management after THA.

Clinical Management of Acute, Closed Displaced Intra-Articular Calcaneal Fractures

Performing a thorough clinical evaluation following an acute displaced intra-articular calcaneal fracture is paramount for optimal surgical timing and long-term outcome. Initial survey must entail a comprehensive evaluation to rule out concurrent injuries. Focused lower extremity examination must involve a complete neurovascular and soft tissue evaluation to identify such conditions as compartment syndrome or compromised integument, which necessitate urgent intervention. Establishing baseline radiographs and advanced imaging is vital for surgical planning. Once deemed stable, protocol-driven treatment is best to ensure proper control of pain and edema and adequate management of economic and patient safety concerns.

Updates on Multimodal Analgesia for Orthopedic Surgery

Pain control after orthopedic surgery is challenging. A multimodal approach provides superior analgesia with fewer side effects compared with opioids alone. This approach is particularly useful in light of the current opioid epidemic in the United States. Several new nonopioid agents have emerged into the market in recent years. New agents included in this review are intravenous acetaminophen, intranasal ketorolac, and newer nonsteroidal anti-inflammatory drugs, and the established medications ketamine and gabapentinoids. This article evaluates the evidence supporting these drugs in a multimodal context, including a brief discussion of cost.
